hopatch – Load patches for packages

Hopatch pro­vides a com­mand with which the user may
reg­is­ter of patch code for a par­tic­u­lar pack­age. Hopatch
will ap­ply the patch im­me­di­ately, if the rel­e­vant pack­age has
al­ready been loaded; oth­er­wise it will store the patch un­til the
pack­age ap­pears.
